Pseudogastroparesis as a presentation of small-bowel malignancy

Establishing the diagnosis of small-bowel malignancy is sometimes an extremely difficult challenge owing to its non-specific symptoms. The mainstay of treatment is early recognition, diagnosis and surgical resection. The prognosis depends primarily on the degree of spread and stage at presentation. We present two cases with initially obscure presentations of a small-bowel tumour. One was a jejunal adenocarcinoma, but an initial upper gastrointestinal and small-bowel series did not disclose the lesion; the other was a primary ileal lymphoma, first thought to be diabetes mellitus gastroparesis. Therefore, a negative small-bowel series or presentation of a systemic disease-associated intestinal pseudo-obstruction or gastroparesis does not exclude the possibility of a small-bowel malignancy, if the clinical symptoms are not alleviated after prokinetic medications. The clinicians should further pursue the possibility of an obstructing lesion.
